Reserva Natural do Sapal

Vast salt-marsh nature reserve with flamingos and working salt pans

The reserve covers more than 2,000 hectares of tidal mudflat, salt pan, and dry scrub along the Guadiana estuary — the first nature reserve created in Portugal, designated in 1975. It is on a major migration route, and the bird list runs to over 200 species: greater flamingo, spoonbill, white stork, kentish plover, avocet, and a healthy population of breeding little terns.

The visitor centre at Cerro do Bufo, about 2 km out of town, has hides and a short interpretive trail through the salt pans. The best months for birds are March to May and September to November; flamingos are present year-round but most numerous in autumn. The working salt pans here produce flor de sal sold across Portugal — guided tours of the harvest run in July and August.

A story
The salt has been worked here continuously for over two thousand years. The Phoenicians took it, the Romans built infrastructure to ship it, and the current Salmarim cooperative still harvests fleur de sel by hand using techniques essentially unchanged since the Moors refined them in the 9th century.
